Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170772, here are decompositions:
- 5 + 170767 = 170772
- 11 + 170761 = 170772
- 13 + 170759 = 170772
- 23 + 170749 = 170772
- 31 + 170741 = 170772
- 61 + 170711 = 170772
- 71 + 170701 = 170772
- 83 + 170689 = 170772
Showing the first eight; more decompositions exist.
